A species often cited as P lanceana but that name is a synonym and is no longer valid

" Variable in size vegetatively, the raceme being shorter than to much longer than the leaf. The sepals are a shade of Yellow orange, while the synsepal is conspicuously suffused with brown below the middle. The sepals are variously ciliate and the calli of the lip vary in different proportions." Luer 2004
